Description

홀소우{HOLE SAW}HOLE SAW {HOLE SAW}

본 고안은 비교적 직경이 큰 구멍을 뚫는데 사용되는 홀소우(Hole Saw) 즉, 구멍가공용 톱에 관한 것으로, 제작성을 향상시키고 원재료의 낭비를 최소화 시키므로서 원가절감에 따른 경제성을 제공하고자 함에 주안점을 둔 것이다.The present invention relates to a hole saw that is used to drill a relatively large diameter hole, that is, a saw for a hole. The main point of the present invention is to provide economic efficiency due to cost reduction by improving the manufacturability and minimizing waste of raw materials. It is put.

홀소우라함은 비교적 두께가 얇은 금속철판등에 구멍을 뚫는데 사용되는 원통형상의 톱을 뜻하는 것으로, 흔히 직경이 큰 구멍을 뚫는데 사용되는데 즉, 홀소우는 기본적으로 톱날이 원통형상으로 구성되어 있고 톱날의 중앙부에는 구멍가공시 위치결정과 중심축 역할을 하는 별도의 드릴이 일체화로 결합되어 완성된 홀소우를 이루게 된다.The hole saw refers to a cylindrical saw used to drill a relatively thin metal plate, and is often used to drill a large diameter hole. The hole saw basically consists of a saw blade having a cylindrical shape and a saw blade. At the center of the hole is a separate drill that acts as a positioning and central axis during the hole is combined to form a complete hole saw.

한편 종래 홀소우는 도4에서 도시한 바와 같이 톱날(1)은 드릴(2)이 나사결합되는 드릴결합부(3)가 상부에 형성되고 그 내부는 공간부(4)로서 비어 있는 것으로 이와 같이 비어 있는 공간부(4)는 별도의 절삭가공기에 의해 내부를 절삭가공하므로서 원통형이 되었던 것이다.On the other hand, as shown in FIG. 4, the saw blade 1 has a drill coupling portion 3 on which the drill 2 is screwed, and the inside thereof is empty as the space portion 4, so that the saw blade 1 is empty. The space portion 4 has been cylindrical by cutting the inside by a separate cutting machine.

즉, 종래 톱날(1)을 형성함에 있어서는 내부가 막혀있는 원형봉(5)을 모재로 하여 소정의 길이로 절단한 후 둘레면이 소망하는 톱날(1)의 두께가 되도록 그 내부면을 절삭가공하고 또한 하측 끝 둘레면에는 산(山)형상의 날을 형성시킨후 열처리를 하므로서 강한 재질의 톱날(1)을 얻었던 것으로, 내부의 비교적 넓은 면적의 공간부(4)가 절삭기에 의해 절삭가공되므로 재료의 손실이 매우 컸으며 또한 날(1a)을 형성하는데도 시간의 손실을 가져왔던 것이다.That is, in forming the saw blade 1 in the prior art, the inner surface is cut to a predetermined length with the circular rod 5 blocked as a base material, and the inner surface is cut so that the circumferential surface becomes the thickness of the saw blade 1 desired. In addition, the lower end circumferential surface was formed with a mountain-shaped blade and then heat-treated to obtain a strong saw blade (1). The relatively large area of the space (4) is cut by a cutting machine. The loss of material was very large and also resulted in a loss of time in forming the blade 1a.

본원 고안은 재료의 낭비가 최소화되고 또한 제작이 용이한 홀소우를 제공하므로서 제작성의 향상과 경제성을 갖고자한 것으로 이에 따른 구성 및 작용, 효과를 설명하면 다음과 같다.The present invention is intended to have improved productivity and economics by minimizing waste of materials and providing easy-to-manufacture. The construction, operation, and effects thereof will be described below.

도1은 본 고안의 실시예로서 톱날과 드릴을 나타낸 분해사시도이고, 도2는 본 고안의 톱날과 드릴이 결합된 조립단면도이며, 도3은 본고안의 톱날의 제작과정을 개략적으로 나타낸 단면도로서 이하 종래구조와 동일부분에 대하여는 동일부호로 설명한다.Figure 1 is an exploded perspective view showing a saw blade and a drill as an embodiment of the present invention, Figure 2 is an assembled cross-sectional view of the saw blade and the drill of the present invention, Figure 3 is a cross-sectional view schematically showing the manufacturing process of the saw blade in the present invention The same parts as in the conventional structure will be described with the same reference numerals.

본 고안의 홀소우는 날(1a)을 갖는 톱날(1)과 톱날(1)의 중앙부에 끼워져 중심축 역할을 하는 드릴(2)로 구성된다.The hole saw of the present invention is composed of a saw blade (1) having a blade (1a) and a drill (2) inserted into the central portion of the saw blade (1) to serve as a central axis.

톱날(1)은 도1내지 도3에서 도시한 바와 같이 밴드형의 톱날이 원통형으로 말아져 그 상부가 결합부재(10)측에 끼워져 결합되며, 결합부재(10)의 중앙부에는 드릴(2)이 나사결합될 수 있도록 나사선(11)이 형성된다.As shown in Figs. 1 to 3, the saw blade 1 is rolled into a cylindrical saw blade, the upper portion of which is fitted into the coupling member 10 side, and is coupled to the center portion of the coupling member 10. The screw thread 11 is formed so that it may be screwed together.

한편, 상기한 톱날(1)은 도3에서 도시한 바와 같이 기 열처리 가공되어 두루마리형으로 감겨진 밴드형의 톱날(100)을 소망하는 직경의 크기만큼 절단한 후 둥굴게 말아 상부를 결합부재(10)의 하부 톱날끼움부(10a)에 끼워 결합시킨다.On the other hand, the saw blade (1) is a heat treatment process, as shown in Figure 3, the band-shaped saw blade 100 wound in a roll shape wound to a size of the desired diameter and then rolled round the upper coupling member ( Fit into the lower saw blade fitting portion (10a) of 10).

그 후 둥굴게 말아진 톱날(1)의 접속부(1b)를 서로 맞대어 용접하고 또한 톱날(1)과 결합부재(10)의 접속부(10b)도 용접을 하므로서 결합부재(10)와 톱날(1)이 일체화가 되도록 하면 된다.Thereafter, the connecting portion 1b of the rounded saw blade 1 is welded to each other, and the joining member 10 and the saw blade 1 are also welded by welding the saw blade 1 and the connecting portion 10b of the coupling member 10. This may be integrated.

이와 같이 된 본원고안의 홀소우는 기 열처리가공된 톱날을 절단하여 사용하므로 제작이 간편하여 생산성이 향상되며, 또한 종래 톱날을 형성하기 위하여 모재의 내부를 절삭가공하므로서 발생하였던 재료의 손실이 없기 때문에 경제성을 갖는 것으로 원가의 절감을 꾀할 수 있는 것이다.Since the hole saw in the present application is used by cutting the heat-treated saw blade, it is easy to manufacture and the productivity is improved. In addition, there is no loss of material generated by cutting the inside of the base material to form a conventional saw blade. By having a cost can be reduced.
